Original application November 1, 1943, Serial N0.

508,575. Divided and this application September 24, 1945, Serial No.618,315

This invention relates to floor drains adapted to be positioned in aconcrete floor and secured to the upper end of a waste conduit of aplumbing installation and is a division of my application Serial No,508,575, led November 1, 1943, (Patent No. 2,400,070, May 14, 1946).

The device disclosed herein includes a perforate basket extending intothe open end of the waste conduit of such character as to prevent coarseWaste material from being discharged thereinto.

These and other features and objects of the invention are hereinaftermore fully described l and claimed and shown in the accompanying drawingin which- Fig. 1 is a vertical section showing the device applied to awaste conduit.

' Fig. 2 is a similar View showing an alternative form of construction.

As shown in Fig. 1 the device consists of a cylindrical body l having aperipheral flange 2 at its upper end to which is secured a flange 3 ofthe head 4 carrying the grating 5 which is positioned substantially withthe upper surfate of the floor 6. The head 4 has an inwardly anddownwardly inclined imperforate flange 1 providing a central opening 8approximately equal to the inner diameter of the waste conduit 9 towhich the flange 2 is secured in any approved manner but preferablyformed integral therewith as shown. On this flange 1 of the head 4 issupported a perforate basket I having an outturned flange I at its upperend terminating in a downwardly extending rim I2 resting on the flangel. The grating 5 has a central aperture to receive the upper end of atube I3 extending in a vertical position and the lower end threaded in athreaded opening centrally of the bottom of the basket.

The material flowing through the grating 5 includes water and a certainamount of debris and enters the basket I0 and the water dischargestherefrom through the openings I4 therein. When the basket becomeschoked with debris the grating 5 may be removed thereby providing accessto the basket and permitting removal thereof by the tube I3 to permitcleaning. The space I5 between the' conduit 9 and the body portion I isusually filled with concrete or caulked with lead and the upper end ofthe waste conduit 9 is covered by the inclined flange I which preventsthe hand of the workman coming in contact with the rough upper open endof the conduit 9 and further prevents floating material fromaccumulating on the ragged upper end thereof.

4 Claims. (Cl. 18,2-31) As shown in Fig. 1 the flange 2 of the body and3 of the head are positioned in the concrete floor 6 and an aperture 6ais provided in the'flange 3 adjacent the vertical portion of the head 4to permit water accumulating in the concrete iloor above the flashing 4ato pass therefrom.

In the alternative form of the invention shown in Fig. 2 a head I6 isformed with an internal flange 20 to receive the inclined flange I1 ofthe basket I8 which is provided with apertures I9 for the same purposeas described relative to the apertures I4 of Fig. 1. The head, as shownin Fig. 2, has an inner flange 20 and the flange I'I of the basket isformed with an outturned terminal edge 2| resting on the flange 20 andany water accumulating in the concrete floor 22 can pass through thepassageway 23 into the drain.

Thus, in either of the forms of the invention shown, the flange II andthe flange I1 arerespectively spaced from the downwardly inclined flange'I or 24 which, in either case, prevents surface contact of the flangeII or I1 with the flange 1 or 24 of the head and prevents the basketfrom becoming sealed, as by rust, to the respective flanges I or 24 andtherefore permits ready removal of the basket subsequent to removal ofthe grating 5 and tube I3 which tube is threaded in the aperture 25 inthe bottom of the basket through which it projects.

It is believed evident from the foregoing description, that in either ofits forms, the device is comparatively simple in construction andfunction alike in respect to separating the debris from inowing liquidand: provide for removal of debris with the basket which, in eitherform, is readily removed subsequent to the removal of the grating andare further alike in the provision of means for preventing accumulationof water on the seepage apron 4a or 4b'in the respective forms of theinvention shown.

Having thus briefly described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is:

1. A drainage fitting for positioning in a concrete floor comprising ahollow body member having an external flange at its upper end and meansat its lower end for centering the same with respect to a drainageconduit, a head having an external flange intermediate its' endsoverlying and secured to the external flange of said body, 'a gratingremovably supported by said head, .a seepage apron in said floorpositioned between said external flanges and having an openingapproximately of the same diameter as the open upper end of said body,said head having a downwardly and inwardly inclined flange at itsterminal edge overlying the upper end of the conduit, a basket having anexternal ange at its upper end supported in spaced relation with theinwardly inclined flange of said head, the basket having a series ofopenings in its wall and an opening centrally of the bottom thereof, anda tube having one end loosely positioned in an opening provided thereforin said grating and detachably secured at its opposite end to saidopening in the bottom of the basket.

2. A drainage tting for positioning in a concrete floor comprising abody having an external peripheral flange at its upper end, a headhaving an external peripheral flange overlying said external body flangeand a downwardly and inwardly inclined flange, a seepage apron in saidfloor having an opening approximately the same diameter as the openingin said body and secured between the said external flanges, means on thebody for ,centering the same in respect to a waste conduit, a gratingremovably supported by said head, a basket having an external flangesupported by the head in spaced relation with the inwardly inclinedflange of said head, the head having an aperture providing for flow ofseepage from within the floor to between the flanges on the head and thetop'inner wall of said body and thence into said conduit, a tube havingits upper end extending into an aperture provided centrally ofthegrating and secured 'at its other end in an'aperture provided thereforin the bottom of said basket whereby said basket may be easily removedfrom said head.

3. A drainage fitting for positioning in a concrete floor comprising abody member having an external flange at its upper end, means at thelower end for securing the same to a waste conduit, a head including aremovable grating positioned lwithin its upper end and having anexternal flange therebelow adapted to be secured to said external bodyflange, said head having an interior vertical wall, `an internal upperflange integral with said wall, said drain head having an internallyprojecting downwardly inclined lower flange overlying the upper end ofsaid conduit, a perforate basket having an external ange supported uponsaid upper internal head ange, and a tube having its upper endpositioned in an opening centrally of said grating and opening at itslower end through the bottom of said basket, the lower end of said tubebeing threadably joined to said basket in the opening in the bottom ofsaid basket. v l v 4. A drainage fitting for positioning in a concreteoor comprising a hollow body member having an external ange at its upperend and means at its lower end for centering the same with respect to adrainage conduit, a head having an external flange intermediate its endsoverlying and secured to the external ange of said body, a gratingremovably supported by said head, said head having la downwardly andinwardly inclined flange at its terminal edge overlying the upper end ofthe conduit, a basket having an external ange at its upper end supportedin spaced relation with the inwardly inclined flange of said head, thebasket having an external ange at its REFERENCES CITED The followingreferences are of record in the le of this patent:
